Hi,
Thank you so much for the info. So thoughtful. I also need to know about all the deductions which will come in to play persay income tax, social security, retirals etc. One of the aim of travelling abroad for work is saving, it would be helpful for me to calculate how much I would be able to save if I know the basic deductions. Kindly give an outlook of how much percentage of deduction I have to bear
